Abstract

An apparatus for receiving broadcasting signals, which comprises first and second audio broadcasting signal receiving portions for receiving respectively first and second audio broadcasting signals, at least one of which is a digital audio broadcasting signal, to obtain first and second reproduced sound signals, each of which may represent substantially the same audio program information, a reproduced signal selecting portion operative to derive selectively the first and second reproduced sound signals obtained from the first and second audio broadcasting signal receiving portions, respectively, a level difference detecting portion for detecting a difference in level between the first and second reproduced sound signals and producing a level difference detection output signal representing a detected level difference, and a signal control portion operative to control one of the first and second reproduced sound signals in response to the level difference detection output signal so as to reduce a difference in level between the first and second reproduced sound signals derived selectively through the reproduced signal selecting portion.
